| - | ===== A LiteMage troubleshooting case study: "Loggin/logout" issue, "compare" issue and "banner" disappears issue ===== | + | ====== A LiteMage Troubleshooting Showcase ====== |
| - | In this troubleshooting case study, we will show you multiple issues(including "Loggin/logout" issue, "compare" issue and "banner" disappears issue), troubleshooting processes and recommended solutions to fix them. | + | |
| - | ==== Issue 1: Login/Logout issue ==== | + | In this troubleshooting showcase, we will be looking at a case where a Magento site was having login/logout issues, comparison issues, and disappearing banner issues as well as the troubleshooting processes and recommended solutions to fix them. |
| - | At Home page, there is one section at the top which says **"Welcome Login or Create an Account"**. With LiteMage enabled, If a user is logged in, it shows "Welcome Sam! Login or Create an Account" While it should show "Welcome, Sam Logout!". Some time, LiteMage caches " Welcome, hole login or create account " if no one is logged in or it caches "Welcome, hole Logout" if a user is logged in. In that case, for other users which just opened the home page, it shows, "Welcome, Logout". | + | |
| - | The user uses theme SM Market. It looks like a template problem. Basically, we need to punch a hole for that piece of info together with the login button, with welcome tag. | + | It is assumed that you are already familiar with Magento Layouts, blocks, and templates as well as how to make proper changes to them. You can find out more from the [[http://devdocs.magento.com/guides/m1x/magefordev/mage-for-dev-4.html|Magento 1.x Developer Reference]]. |
| - | Global PHP variables can not be initialized in header.phtml and social.phtml, update those two files: | + | ==== Issue 1: Login/Logout ==== |
| - | /home/user1/public_html/domain1.com/app/design/frontend/sm_market/default/template]# vi page/html/header.phtml | + | |
| - | /home/user1/public_html/domain1.com/app/design/frontend/sm_market/default/template]# vi page/html/social.phtml | + | |
| - | by adding the following to the top of the template(please be aware that that Varable name could be different to the example): | + | |
| - | if (empty($var_yttheme)) { | + | On the home page, there is a "Welcome/Login/Create an Account" section at the top. If a user logs in, we expect to see something like ''Welcome, Sam! Logout''. With LiteMage installed, we were instead seeing ''Welcome Sam! Login or Create an Account.'' In this case, LiteMage cached ''Welcome, <punched_hole>! Login or Create an Account'' for a logged out user and served that to the logged in user. |
| - | include (dirname(dirname(__FILE__)).'/sm/yt_prepar.php'); | + | |
| - | } | + | |
| - | + | ||
| - | according to [[litespeed_wiki:cache:litemage:troubleshooting:uninitialized-php-vars-injected-block|this wiki]]. | + | |
| - | After initialization problem resolved, we need to punch a big hole instead of small one. In MagentoAdmin LiteMage config, enter "header" in Customized Block Names for "toplinks" Tag. | + | This issue was also happening in reverse! LiteMage would instead cache ''Welcome, <punched_hole>! Logout'' for a logged in user, serving ''Welcome, ! Logout'' to non-logged in users. |
| - | ==== Issue 2: compare issue ==== | + | Looking further, we see that the user uses the SM Market theme. It looks like a template problem. |
| - | Put "compare" in Additional Purge Tags for "toplinks" Blocks. | + | We need to punch a hole for that piece of info along with the login button and welcome tag. (**[[litespeed_wiki:cache:litemage:troubleshooting:checking-hole-punching|How to check hole punching]]**) |
| - | ==== Issue 3: banner disappear issue ==== | + | Since LiteMage processes these ESI blocks in small chunks, some global PHP variables initialized in header.phtml and social.phtml were not available in these chunks. These two files needed to be updated to initialize them: |
| - | The above solutions fixed Loggin/logout user showing wrong info issue. But due to the changes, the banner disappears from homepage. | + | |
| - | After further investigation, we found out the header template includes logic to check if it's frontend or not. If it is frontend, then it show banner. So we cannot simply punch a big hole for the header. | + | <code> |
| + | /home/user1/public_html/domain1.com/app/design/frontend/sm_market/default/template]# vi page/html/header.phtml | ||
| + | /home/user1/public_html/domain1.com/app/design/frontend/sm_market/default/template]# vi page/html/social.phtml | ||
| + | </code> | ||
| + | |||
| + | The following was added to the top of the two templates | ||
| - | The solution is go back to fix the login links. We basically needs to single out the logic and put it in its own block so we can hole punch it as a private block. The rest can be publicly cached. | + | <code> |
| + | if (empty($var_yttheme)) { | ||
| + | include (dirname(dirname(__FILE__)).'/sm/yt_prepar.php'); | ||
| + | } | ||
| + | </code> | ||
| - | Copy original files as .bak. | + | according to our **[[litespeed_wiki:cache:litemage:troubleshooting:uninitialized-php-vars-injected-block|Uninitialized PHP Vars In Injected Blocks]]** page. |
| - | Header style selection is “header4” | ||
| - | Inside [app/design/frontend/sm_market/default/template/page/html]vi header4.phtml, We can see the logged-in link is mixed in the header template. We need to take that logic out and put in its own block and template, so we can punch a hole for that block. | + | ==== Issue 2: Punching A Bigger Hole While Still Purging Private Sections ==== |
| - | <div class="yt-header-top"> | + | Now that the initialization problem is solved, we need to punch a big hole instead of small one. Logging into the Magento Admin and entering LiteMage config, we add "header" in **Customized Block Names for "toplinks" Tag**. |
| + | |||
| + | We also see "compare" in a toplinks block, so we add "compare" to **Additional Purge Tags for "toplinks" Blocks** as well. | ||
| + | |||

| + | |||
| + | |||
| + | ==== Issue 3: The Case of The Disappearing Banner ==== | ||
| + | |||
| + | At this point we have fixed the login/logout issue. Great! Except now the banner has disappeared from the homepage. | ||
| + | |||
| + | After some further investigation, we found that the header template included logic to check if it is displaying on a frontend page or not. If it is not a frontend page, then the banner will not display. This stops us from simply punching a big hole for the header, like we did earlier. | ||
| + | |||
| + | We now needed to go back and "fix" the login links. | ||
| + | |||
| + | After making a copy of ''header4.phtml'', the header style file, we open it to begin modifying. | ||
| + | |||
| + | <code> | ||
| + | [app/design/frontend/sm_market/default/template/page/html]vi header4.phtml | ||
| + | </code> | ||
| + | |||
| + | Inside we can see the "log in" link mixed into the header template. That logic needs to be taken out and put in its own block/template so we can both hole punch it as a private block AND keep the rest of the header publicly cached. | ||
